I was injured in a Michigan car accident and need someone to care for me while I recover. Does my insurance company have to pay for this service?

Yes, if a doctor prescribes what is called "attendant care services." The car insurance company must pay a reasonable hourly rate for the service, even if it is being provided by a family member. The person is entitled to payment for being "on call" when you sleep, if you need supervision or assistance with toileting.
